Primo Maxx Turf Growth Regulator

Primo Maxx is a powerful plant growth regulator (PGR) designed to promote denser, healthier turf that thrives under stress from heat, drought, disease, and traffic. By inhibiting gibberellic acid production, Primo Maxx slows vertical growth while stimulating root, stolon, tiller, and rhizome development, resulting in a stronger, more resilient turf canopy.

Ideal for managing hard-to-mow areas, reducing the need for edging, and conserving water, Primo Maxx helps turfgrass maintain its health and appearance with less maintenance. It’s also effective in overseeding programs where Poa annua is present and offers pre-stress conditioning for better performance during extreme weather.
